I have made some more tests. First the package looks ok, but it does
not work because the /usr/lib/tls directory is used inconditionnaly.
This is because ld.so actually does not actually check for TLS hwcap
(which does not really exists), but only check the OS ABI. All libc6
libraries in this directory are tagged "OS ABI: Linux 2.6.0".
I will try to have a look for a patch to add this note to libstdc6++
Then I have made some more tests on all Debian architectures:
Architecture MIN_KERNEL NPTL flavour TLS status
-----------------------------------------------------------------
amd64 2.6.0 No TLS working
alpha 2.2.0 No TLS working
arm 2.2.0 No TLS not supported
hppa 2.2.0 No TLS not supported
i386 2.2.0 Yes TLS fails on 2.4 kernels
ia64 2.2.0 Yes TLS working
m68k 2.2.0 No TLS not supported
mips 2.2.0 No TLS not supported
mipsel 2.2.0 No TLS not supported
powerpc 2.2.0 NPTL flavour TLS working
s390 2.4.1 NPTL flavour TLS working
sparc 2.4.18 No TLS working
On 2.4 kernels, the linuxthread flavour which does not support TLS on
i386 is used. On 2.6 kernels, the NPTL flavour is used. So it looks
like this flavour is actually only needed on i386.
Bye,
Aurelien
